大卫兄上次你讲和AT的厂家交流后决定买C-Q系列的4寸,我见FLEXUNITS的4H520613的频响曲线比C-Q系列的4寸平直很多呀,C-Q的4寸在1KHZ以后就开始升高了,2K多HZ升高了好多。请教老兄C-Q比FLEXUNITS好在哪呢?
我给AT提出的4寸中音要求如下
(a) Cone diameter: 4-inch, identical cone with Guaraneri woofer
(b) Nominal Impedance: 8 ohms
(c) Overhung voice coil with Kapton voice former
(d) Symmetric Drive and H magnet
(e) Sensitivity: not lower than 90 dB at 1 Watt/1M during the frequency range set below
(f) Frequency range: 300~6000HZ
PER的回答如下
The cone of the Guarneri driver, is our standard Flexunits cone. Please note, the circular pattern on the cone is made by Sonus Faber and can therefore not be applied by us. It has no sonic effects – only optical.
Regarding the cocktail: SD system, Kapton former and the 4” Flexunits cone, we have experience the response may be troublesome. It can differ from driver to driver, where using the C-Quenze cone, we have no problems. The Flexunits cone in combination with alu bobbin is also safe.
The Flexunits cone rolls off at 5,5 KHz but the C-Quenze cone runs a bit higher.
Please reconsider using the C-Quenze cone, as it seems a better cone for your project. |
